Question

R Σ Two lined AB and CD intersect at O. If angle COB+angle BOD + angle AOD = 270 ,then angie * O 180 90 O 120 O 270​

Answer 1

Answer:

bro 90° degrees is the answer

Step-by-step explanation:

Let ∠AOC=x and ∠COB=y. Then, ∠BOD=x and ∠DOA=y.

Now, ∠AOC+∠COB+∠BOD=270

∘

⇒x+y+x=270

∘

⇒2x+y=270

∘

But, x+y=180

∘

∴x=y=90
